Free flowing direct-fit resonator-back system cuts backpressure. Throaty sound; huge polished tip. Ford 3.5L EcoBoost. Constructed from heavy-duty stainless steel, Banks' large bore, mandrel-bent Monster exhaust system connects to your truck's factory intermediate pipe, cutting backpressure and increasing flow. That gives you the best of all worlds - increased power, greater longevity and maximum fuel efficiency. The polished-stainless straight-through muffler outflows stock by a mile and delivers a commanding, yet civil, exhaust note. This system has been specifically developed to work with the factory resonator (where equipped) to eliminate in-cab drone and resonance which can be very pronounced on variable cam timing V6's, while maintaining a throaty performance sound. The system includes Banks' exclusive ob-round (patented design) angle-cut rolled-edge tailpipe tip in your choice of polished chrome-over stainless or high-temp black! And to help keep it looking good, there's a 1/2 inch air gap to keep heat from tarnishing the finish. An adjustable clamp lets you position it on the tailpipe just right. The lightweight, direct-fit-system bolts on easily. Looks great on the Tremor! Fully compatible with Ford's factory warranty and so durable that it's covered by Banks' 5-Year Limited Warranty!
